swapping in tank fuel pumps

FoxHole · Nov 5th, 2005, 08:22 AM

Hello. I just bought a 95 nissan pickup 2.4 4x4. It was made in 9-94 and the in tank fuel pump was locked up. I took it apart and freed it up but dont know how to seal the tube back because it was originally crimped from factory. I went to get a new one and they want 200$. I was wondering if there is another in tank pump with the same psi rating (33psi) from another vehicle that is cheaper that i could use to replace this one. also would like to know if they make an out of tank fuel pump that puts out the 33 psi needed. Thanks much. FoxHole

i have never "rebuilt" an intank pump,so dont know about the crimp. you can buy aftermarket pumps that mount to the framerail that are adjustable for psi, but that would be more expensive than using the correct part. i would recommend you just replace the pump, they do wear out you know. i wouldnt risk rebuilding my old one.

Thanks for the reply. I talked the guy at the parts store into a 10% discount and the little thing still cost $205.00 then they got me for another $15 for the little nylon screen filter. I am now waiting on the plastic check valve to come in that i ordered online. I broke the brittle old one when removing it. It will be another$22. Man these little parts are expensive but now i have a lifetime warrantee pump but you have to buy a new screen filter every time you bring the pump in for replacement or the warrantee is void. I cleaned the tank out and took all the old paint off. I welded a couple of pinholes up and then covered the tank with fiberglass resin. I then painted it flat black enamel. The in tank device that the pump mounts to was corroded and i cleaned it with a dremil tool and the wires inside were corroded and not making contact. I soldered a couple of them together. After tearing the old pump apart and watching it work again, it made me wonder why any one would ever invent a fuel pump that pumps gas directly through the windings and brushes of the pump motor. Doesn't this seem like there could be a chance of explosion? lol.

I hope you got ALL the pinholes! If gas comes into contact with that fiberglass your in for alot more headache... If you want a guaranteed LEak-Free tank, which I assume you do by the steps youve already taken.. Then you need to invest in some POR-15 tank liner.. Cost's about $100 to do a full-size tank but so far Ive done 3 that had some pretty decent leaks and their still going strong.. I think theres some lifetime guarantee if properly done..

And NOPE....NO danger in having fuel go through the winding.. Fuel needs air to combust (ignite).. Remember that its the fumes that'll get you in trouble and that ignite in the cylinder.. Even if the tank is low on fuel its either in a vapor or pressure situation where it'd be nearly impossible to ignite.

To answer the original question, you have to buy a new pump, and it runs at 46+ PSI, not 33.
