welder u know i worried about the clogging with cold veggie but despite i used them anyways without purging them and no heat source they pump the cold veggie out fine but i mount them right beside the filter so the hot veggie gets in them fast this winter will be the true test for that... 2 in series hhmm i think 1 does fine 2 wouldnt hurt atleast youd have a back-up if one failed but i think 1 is enough... i did think about putting 2 of them parallel with a pressure switch and and a simple timmer so when the psi got to low the second pump would kick on to boost pressure back up and a timer to alternate between the pumps every 30 mins or something like that to give them time to cool down since a long trip is hard on 1 pump running hours on end buddy went thru 2 pumps in a week and half before i put the procomp on his truck

I use generic/universal elec fuel pumps I get from autozone. Not the ones on the floor/aisles but the ones you gotta ask the parts guys for (the old parts guy that actually knows what you are asking for, not the dumb teenager)....
About $35 for a low psi pump. I've even found that the engine will still run if these Autozone pumps lose power....I've installed right before the filter and have disconnected the power wire while the engine is running and it just keeps on running without the fuel pump on....but that is idle so I can't say for driving fuel flow requirement....seems these pumps I can blow air thru the input side but not backwards....guess they will also allow the IP to pull/suck fuel thru it if they loose power. 1983 Holiday Rambler 6.2 Banks TD for sale 1987 Mercedes 300TDT 1983 Maxima wagon LD28 for sale 1985 D50 Ram 2.3 TD 1984 Isuzu P'up longbed diesel |

Has anyone experimented on the plunger type in line pump by airtex?I've been using one for a year so far no problem.Is this better than a vane?Thanks.

Vanes, pistons and gears are all positive displacement pumps.
I think the only significant problem you might run into might be overheating the pump motor due to a combination of workload and heat from the hot veggie. |

Any updates on this? Anyone with some miles logged? Thanks for all of your great research Tim & Welder. Tigafila

I'm not completely sold on any particular approach.
I've heard that a Holley Blue with modded vanes is okay. I figure that Tim is on the right track also with the Suntec. I finally got ahold of Ken Gardner and I will get some details from him regarding his success with the Shur-Flo #2088. I'm tempted to wire some cash down to Rick at GreaseKings to ship me up some cheap Master brand solenoid piston pumps. I'm also tempted to buy a serious all out hydraulic gear pump that can make 2000 psi and rig it up to my scooter motor. No fiddling with internal valves would be required there (there aren't any). If I do, I'll likely mill off about 1/2 of the wall thickness and brase a stainless water jacket around the guts for some sort of pre-heat. The trick is finding a regulator that can take huge intake pressure at 200 degrees F and reduce it to 6psi. I've got some leads, but we'll se what happens. It's very slow progress. I'll fill you in as things unfold. |

Hi Welder, I'm intrested in the info on the shurflo 2088 pump as well. I have not been able to find much info on them in Australia but have heard they are reliable for wvo/svo. They price they get here is high so I want to find as much info as possible before I part with my cash. It will also save money to buy the pump direct from USA and cut out the middle man who imports them to oz, do you know where I could purchase one?
Thanks froggo HJ45 Toyota Landcruiser Troopcarrier running WVO, 2tank homemade system. |

Pretty true, I'd say. There's ways around it. |

I think Tim's been busy lately. Why not PM him and ask him for an update?
I've been getting parts together very slowly. My new pump head just arrived (I abandoned the old Suntec in favour of a different pump). Now I've got some custom machining to do to get the shafts to mate properly. |

I've gotten several Walbro FRB-5 pumps, but i haven't installed mine yet. Anyone else installed theirs? The Walbro 6065 I'm using now is working very well, one year and no problems.

Hi B.K. I'm curious why you bought a bunch FRB-5 pumps if your 6065 still runs good? Planning more conversions? |

I bought more FRB-5's because the 6065 was not available (not made anymore) and the replacement is the FRB-5. I decided i better get one to have, so if/when the 6065 DID fail, I had an on-hand replacement part. As it turned out, I replaced it and it did die while pumping cold WVO from one barrel to another. The FRB-5 seems to be doing fine. I did find and buy a brand new (old stock) 6065 as my next replacement off of Ebay for $30, thanks for the tip curbill!

I got my machinist buddy to spin an adapter piece to mate the drive shaft of the scooter motor to the flexible rubber drive couplers that I bought for this project. The other end of the coupler will mate to the pump drive shaft. I built a base at work to mount the pump and motor on. Hopefully, I can squeeze the fuel pressure regulator on there too. I got bogged down with trying to make or buy the best fittings for this pump. I can't seem to solidly decide between using hosebarbs & hose (easy) or using flared tightly bent aluminum aircraft tubing (harder to build, but better heat absorbing efficiency). On a side note, I bought some nice dessicant breathers for my veggie tank & my purge fuel tank. When I get around to actually welding them, I think I'll weld tabs to them so I can bolt them together for stability. With dimensions like 1'6" tall by 6" wide by 3'6" long and 1'6" tall by 1'wide by 3'6" long, they would be kinda tall & floppy unless I attach them to each other for a combined width of 20" (2" gap for insulation). I'm still redesigning my custom veggie filter. I wasn't happy with the original filter element (Goldenrod threaded tank filter element) and don't really like the second element much better (NapaGold 3210). If anyone knows of a large caoacity drop-in cartridge style filter element with about 5 microm absolute media and 1" or larger openings at each end, please let me know. Will update more when there's something worth reading about... |

I am still considering of using a Suntec for my wvo pump on my 97 7.3 f250. I still am running a malory 110 for now but I don’t expect it to go more than 30K. It would call for about 65 pounds pressure . Now I use an external regulator with the malory and I don’t know if I would or should remove it if or when I switch to suntec. My concern is that what if the pump all the sudden built up to like 150 lbs. I don’t know if that would be possible or not but with the external regulator it could not happen (I think).

Gotta throw my hat in the ring for Delphi pumps. That one is low pressure but they do make higher along the lines of the carter line. They have also updated this model some but it's the tolerance for high temp that makes them an ideal choice for VO.

haveing problems with electric fuel pumps, would gravity feed to the pump help? should prevent overheating and strain on the pump trying to keep it simple and cost and have a pump that u can get at any parts store as far running svo you really cant go wrong my set up is a 96 gmc 6.5 diesel a 2500 and a 3500 4x4 the filter is a basic gm set up which is not that exsensive the best thing you can get a bottle of awsome from dollar general for a dollar to clean the filter works great and does not harm the filter and clean it several times been doing this for about 3 years i used the holley red pump no good for svo the pump is the only problem i have
