Need an inline fuel pump for a multiport fuel injected engine.

We have been using the Holley badged Walbro, but the third one on our two cars just crapped out, so I would like to try a different brand. The trouble is that the only OEM's that I have found are pricey. ($400.00 for a Ford) Don't know why they are going. Fuel filter before and after, good ground and power supply. I have been forced to conclude they are just poorly made.They initially cause the car to miss in the late stages of a long race, but the condition gets worse and after a while, they provide no fuel pressure at all.

Summit has a few hundred different pumps in stock like that, you may want to call in for a recommendation. Assuming you're looking at 255lph EFI pumps, there's 3 others besides the Walbro: Link

the slightly bigger Mallory and Accel pumps might also be a good idea: Link

Thanks for the links. I think they are all the same pump. (Accel, Mallory, Walbro and Holley.) They are identical, with slightly different specs.

Are you using this as a standalone pump?

It seems to be that these pumps need a pre pump to live for any length of time. Now if you wanted you could use one of those Bosch 044 pumps......

I'd call Summit and ask. They usually know who actually manufacturers all of their products so they can usually point you somewhere else. About 6 years ago I was having Walbro issues and they helped me out.

Thats interesting. They are drawing from a fuel cell, so they have to pull almost a foot of static head. Maybe that is killing them.

Often times the pump takes the blame for other fuel system related issues like a too-small return line, no return line, a poor tank vent (pump works too hard), or radiant heat--including from the track surface itself. At the end of the day, nothing beats an in-tank fuel pump.

I see the ford inline pump used a low pressure pump in the tank to feed it.,

If you're lookin for cheap, the late 1980s Ford pick ups with dual tanks had a frame mounted in line pump (next to bell housing on drivers side) to run their 5.0s and 5.8s with multiport efi, should be good for 40-60 psi I'd guess. Maybe you could grab one at a u-pull-it for happy meal money, just to see if it'd do the job...?

Lines are all stock, and the vent line just vents to atmoshpere under back of the car. Its a big line.

We used Pierburg in-line external pumps for years. Bombproof, and they'll move a lot of high pressure fuel - we ran them at 100 psi plus. I think Audi uses them, I seem to remember cross-matching it to the Coupe a few years back. I've got one in the Locost and one in the LS1 MGB.

We don't sell 'em anymore, but I could probably get one. Worldpak 7.21659.70 if you know somebody. I don't know the current pricing, but I'd expect $200-$250.

Ford pump that normally has a lift pump but most race guys don't bother with lift pumps just make sure pump is as low as it can be as to cell height so it only has to suction once then siphons in to the pump. Check e-bay for E2000 or E-2000 pumps I've seen'em cheap like $25 cheap plenty of them are in use in Dwarfs around the track but dependent on your motors needs it may run out on the top end flow wise think Per had an issue show up on a dyno day. some right now for $39.99

MOTORCRAFT # PF4 FORD # E7TZ-9C407-BA AIRTEX # E2000 CARTER # P74028 AC DELCO # EP286 BOSCH # 69100 DELPHI # FE0306

Cheak all the difrent MFG part numbers as some don't list cross ref number in their listings and don't show up in searches etc.

When I was looking for a pump I found you can order these Airtex pumps at your local AutoZone or Advance Auto Parts.

E8248 265LHP / 70 GPH 3/8 hose 120 psi

E8228 144 LHP / 38 GPH 5/16 hose 120 psi

E-2000 155 LPH /40 GPH 5/16 hose 95 psi

E8445 133LPH / 35 GPH 5/16 hose 65 psi

I'd pick Advance since they have tons of coupon codes floating aorund.

Another option is Airtex E2182 190 LPH / 50 GPH which has an 1/2" inlet and 5/16 outlet. I've seen it listed as both an internal and external pump. I'm been running it externally on my 280Z and its been ice cold but I only have 50 miles on it so far. Rock Auto had the best price I could find on this one.

If you need an inline pump that's not $400 and not a Walbro, we have this one, made by Essex Industries in St. Louis:

That reminds me I need to have the one in my possession rebuilt. Only been sitting on my shelf in the original shipped box since 98 or 99....
